Unable to load preload script

[MrTob]

I followed the set-up tour from nx-electron with Angular Now i tried to integrate this Library into the Monorepo, but it didn't work.

//main.preload.ts
import { contextBridge, ipcRenderer } from 'electron';
import { ContextBridgeService } from 'ngx-electron-bridge';

contextBridge.exposeInMainWorld('electron', {
  getAppVersion: () => ipcRenderer.invoke('get-app-version'),
  platform: process.platform,
});

// create a context bridge service
const contextBridgeService = new ContextBridgeService();
contextBridgeService.addIpcBridge("myExposedFunctionSignature", "my-exposed-function")
.addIpcBridge("anotherExposedFunctionSignature", "another-exposed-function")
.expose();

//electron.events.ts
ipcMain.handle("my-exposed-function", (event, ...args) => {
  console.log(args);
});

//app.component.ts
import { Component, Inject } from "@angular/core";
import { RouterModule } from "@angular/router";
import { NxWelcomeComponent } from "./nx-welcome.component";
import { ElectronBridge } from 'ngx-electron-bridge';
@Component({
  standalone: true,
  imports: [NxWelcomeComponent, RouterModule],
  selector: "app-root",
  templateUrl: "./app.component.html",
  styleUrls: ["./app.component.scss"],
})
export class AppComponent {
  title = "angular";

  constructor(@Inject(ElectronBridge) private _electronBridge: any) {
    _electronBridge.myExposedFunctionSignature("hello", "world");
  }
}
